7. ADJUST DIFFERENTIAL SIDE BEARING PRELOAD
(a) Install the differential assembly to the transaxle case.
(b) Clean the contact surfaces of the transaxle case and transaxle housing.
(c) Install the transaxle housing to the transaxle case with the 20 bolts.
Bolt A - Torque : 31 Nm (316 kgf-cm, 23 ft-lbf)
Bolt B - Torque : 23 Nm (234 kgf-cm, 17 ft-lbf)
(d) Using SST, turn the differential assembly right and left 2 or 3 times to settle the bearing.
SST : 09564-33010
(e) Using SST and a torque wrench, measure the turning torque of the differential side bearing while rotating SST at 10 rpm.
SST : 09564-33010
Turning torque:
1.05 to 1.93 N*m (10.70 to 19.67 kgf*cm, 9.29 to 17.08 in.*lbf)
If the turning torque is not within the specified range, refer to the table below to select a shim so that the turning torque is within the specified range.
Shim thickness: mm (in.)
(f) Remove the 20 bolts and the transaxle housing from the transaxle case.
(g) Remove the differential assembly from the transaxle case.
8. INSTALL FRONT DIFFERENTIAL RING GEAR
(a) Using ATF and a heater, heat the front differential ring gear to 90 to 110°C (194.0 to 230.0°F).
NOTICE:
Do not heat the ring gear to more than 110°C (230.0°F).
(b) Clean the contact surface of the front differential case.
(c) Align the matchmarks, and install the front differential ring gear case quickly.
NOTICE:
Do not install the bolts while the ring gear is hot.
(d) Tighten the 12 bolts.
Torque : 120 Nm (1,223 kgf-cm, 88 ft-lbf)
NOTICE:
Tighten the bolts a little at a time in diagonal order.
